<p><P>PROBLEM TO BE SOLVED: To provide technology for simplifying user's login operation to a host server in a karaoke network. <P>SOLUTION: When login is permitted for a registered user, the host server updates a simultaneous login date which other users login, and a simultaneous login history data of the registered user which is stored in a simultaneous login history data base included in a data base based on the other user ID, and a numerical value of the user ID in which the simultaneous login date is the same in the simultaneous login history data of the registered user is extracted and transmitted to a remote control terminal as a login candidate. Then, the remote control terminal displays the user ID of the login candidate so as to be selectable, on a display section. When the user ID is selected, the remote control terminal acknowledges it as input operation of the user ID in order that the host server authenticates the registered user. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
